Solution Overview

Problem

There is a lack of effective therapeutic methods for chronic prostatitis/chronic pelvic pain syndrome, as the etiology of this condition is not well understood, and existing treatments do not adequately address the underlying pathophysiology.

Innovation Solution

Development of a prophylactic and therapeutic agent containing an mPGES-1 inhibitor, specifically compounds of Formula [1] or their pharmaceutically acceptable salts, to target the mPGES-1 pathway, reducing pain and inflammation in animal models of chronic prostatitis/chronic pelvic pain syndrome.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional treatments are used for chronic prostatitis/chronic pelvic pain syndrome, then general symptoms may be managed, but the underlying inflammation and pain pathways are not effectively targeted

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidtreatment mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by targeting a specific biochemical parameter (mPGES-1 enzyme activity) rather than using broad-spectrum treatments. The mPGES-1 inhibitor selectively modulates the PGE2 synthesis pathway, changing the therapeutic parameter from general anti-inflammatory effects to specific prostaglandin E2 pathway inhibition, thereby improving therapeutic reliability for chronic prostatitis/chronic pelvic pain syndrome

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The mPGES-1 inhibitor acts as an intermediary substance that blocks the conversion of PGH2 to PGE2 by inhibiting the mPGES-1 enzyme. This intermediary approach allows selective intervention in the inflammatory pathway without directly affecting other physiological processes, resolving the contradiction between effective symptom management and treatment complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the etiology of chronic prostatitis/chronic pelvic pain syndrome is not well understood, then targeted therapies cannot be developed, but this lack of understanding prevents effective treatment development

Engineering Contradiction:
Improvetreatment adaptabilityVSAvoidetiological information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent applies preliminary action by proactively identifying and targeting the mPGES-1 pathway based on emerging understanding of its role in inflammation and cancer. Rather than waiting for complete etiological clarification, the invention takes preliminary therapeutic action by blocking a key enzyme in the PGE2 synthesis pathway that is upregulated in chronic prostatitis, thereby enabling treatment development despite incomplete etiological knowledge

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention changes the therapeutic parameter from empirical symptom management to mechanism-based targeted therapy by identifying mPGES-1 as a key player in the disease pathology. This parameter change enables treatment adaptability to specific molecular pathways involved in chronic prostatitis/chronic pelvic pain syndrome

Inventive Principle:
Principle #35Parameter changes
